Application July 9, 1936, Serial 1 Claim.

This invention relates to a plastic corner element adapted to form a neat junction or joint between shingles, to overcome the necessity of cutting the shingles otherwise than at a right angle and along straight lines adjacent the corners or the equivalent of the walls of buildmgs.

It is further aimed to provide such an element as may be readily cast or molded from a suitable durable, cementitious or other plastic material preferably containing asbestos.

Various additional objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating an operative embodiment.

In said drawings:-

Figure 1 is a view in side elevation, fragmentarily showing an end of a wall embodying my improvements;

Figure 2 is a cross sectional view taken on the, line 22 of Figure 1;

Figures 3 and 4 are detail perspective views of opposite ends of the corner element used in Figures 1 and 2;

Figure 5 is an elevation similar to Figure 1, of a modified form;

Figure 6 is a cross sectional detail taken on the line B- i of Figure 5;

Figure 7 is a detail perspective view of part of the corner element used in the form of Figures 5 and 6;

Figure 8 is a horizontal sectional view through a third modified form;

Figure 9 is a horizontal sectional view through a fourth modified form;

Figure 10 is a horizontal sectional view through a fifth modified form;

Figure 11 is a horizontal sectional view through a sixth modified form;

Figure 12 is a horizontal sectional View through a further modified form;

Figure 13 is a horizontal sectional view through another modified form, and

Figure 14 is a horizontal sectional View through a final modified form.

Referring specifically to the drawings and first to the form of Figures 1 to 4, a portion of the frame of a building is suggested at it), against which shingles H and are usually of the asbestos type, are nailed as at ii at their lower edges lapping the upper edges of adjacent shingles. In accordance with my invention, corner elements or pilasters are used at E3 and which may be of various forms according to the angles of the walls and the like. Such elements I 3 are preferably cast from any suitable material in a plastic state, usually of a cementitious nature and containing asbestos so as to match the material of the shingles I I, although this is not essential and which material of the elements It, may be colored overlapped by the shingles H, with a bead or corner portion it, projecting outwardly beyond the shingles to cover their edges and form a protection against rain and the like.

These elements l3 preferably have openings [7 provided therein when cast to accommodate the nails l5.

Attention is called to the fact that the corner elements Hi are made in sections, a portion of a portion of the tended as at l9, cut away portions N3 of adjacent elements will form a continuous bead.

The invention may be practiced in various ways and in various forms. For instance as shown in Figure 7, the corner element I311 may be in a the walls are at angles other than right angles. form of Figure 8 over that of the preceding views is in the shape of the corner element I327, it being noted that the flanges Mb are at right angles and that at their junction, the inner surface of the corner element is cut away as at 2! ment is cut away at Figure 10 uses a corner element substantially like that of Figure 11 with the exception of the attaching flanges designated the back as at 22.

Mel of the corner element I3d, being at right angles to each other.

Figure 11 shows another form wherein the corner element |3e has its attaching flanges Me at a right angle to each other and with the bead Hie concave as at 23.

Figure 12 conforms to Figure 11 with the exception that the attaching flanges I l of the corner element I61 are at angles other than right angles.

Figure 13 shows a final modified form wherein the corner element is designated Ifig and the attaching flanges Mg, such element being cut away at the back as at 24.

Attention is called to the fact that in accordance with the present invention, the shingles such as H and Ha do not have to be joined, specially cut or the like since their ends may be arranged in a straight line, usually with alternate shingles being cut on a straight line. I flnd by the present method of providing the corners of the walls of buildings, that about onethird of the scaffolding will be necessary as compared with the usual method of applying the shingles.

Various changes may be resorted to provided they fall within the spirit and scope of'the invention. V V j I claim as my invention:- V

A corner piece of the class described having elongated flanges adapted to be attached to angularly arranged walls of a building, said flanges extending at an angle to each other, arelative- 1y thick bead extending outwardly from the junction of said flanges to provide shoulders extending outwardly from the said flanges, whereby the flanges form inset seats for engagement by shingles or the like adapted to abut said shoulders, said bead terminating short of one end of the flanges and projecting beyond the other end of the flanges, so that adjacent corner pieces may interengage.
